The new PKZM 01 motor-protective circuit-breakers for motors up to 16 A are ideally suited for small machines and applications which are preferably operated using pushbutton or palm switches.

A specia l enclosure with IP 40, IP 55 and IP 65 degrees of protection available as surface mount or installation enclosures, feature protection against direct contact, solid foreign bodies and dust as well as the ingress of water.

Whether equipped with protective membranes, locking devices or the respective emergency-stop button, the methods of actuation leave no wishes unfulfilled.

Engineering and inventory management are facilitated as accessories such as voltage releases, trip-indicating auxiliary contacts and auxiliary contacts from the PKZM 0 range can be used

The tried and tested PKZM 0 now switches motors up to 32 A. Simultaneously, its short-circuit switching capacity has been increased significantly. The short-circuit rating (400 V) is now rated to 150 kA up to 12 A and 50 kA up to 32 A.

The PKZM 4 also has a switching capacity up to 50 kA. It facilitates engineering. Current limiters become practically obsolete.

With just two motor protection variants, the entire range from 0.1 to 65 A is covered. It saves precious inventory space and simplifies the e ngineering effort.

The PKZM 4 with a width of just 55 mm is the narrowest switch for 65 A. Precious space in the control panel is saved!

Accessories: Full functionality with only few versions

The auxiliary contact modules can be fitted without any tools and provide fail-safe information about each switching state. This also applies to the NHI-E auxiliary contact module, which fits within the PKZ and can be mounted from the front. Additional advantage: It is within the unit width and thus requires no space at the side.

Whether it be an integrated auxiliary contact, a trip-indicating auxiliary contact, a voltage release or door coupling handles, the accessories for the PKZM 0 can also be used for the PKZM 4

DILA-XHIR22 – switch small signals reliably

The DILA-XHIR22 front-mounted auxiliary contact from Moeller enables users to switch small signals reliably. One  auxiliary NO contact and one auxiliary NC contact are provided as micro switches. These contacts with their operating range – min. 1 mA at 3 V – are specially designed for signals as they occur in joint operation with PLCs and other electronic components.

Thanks to their dust-tight design DILA-XHIR22 contacts are also suitable for harsh ambient conditions.

DILA-XHIR22 units are also provided with one conventional NO and one NC contact, which are required for tasks such as self-latching. The new auxiliary contact for electronic applications can be combined with DILA contactor relays and DILM7 to DILM38 contactors (7 to 38 A AC-3 at 400 V). Its dimensions are identical with the established front mounting auxiliary contacts. Both NC contacts, as well as the micro switch and conventional contact meet the mirror contact functions according to IEC/EN 60947-4-1 Ann. F. In addition to signaling in electronic circuits, they are particularly suitable for feedback signals in safety applications such as contactor feedback signals in the feedback loop of a safety PLC.

The DILA-XHIR22 front mounted auxiliary contact is approved for use in accordance with UL and CSA so that it can be used worldwide

Our AC and DC contactors DIL M have absolutely perfect dimensions: externally identical just like twins should be. And that for all four sizes up to 170 A. This simplifies planning and engineering.

The compact external dimensions also save precious space in the control panel.
The contactor series up to 38 A even features integrated auxiliary contacts.

At a second glance the inner values are the most important:

• Integrated suppressor

Voltage peaks must be avoided when controlling the contactor directly from the PLC. This is why all DC contactors feature integrated suppressors ex-works. They ensure that very short switch-off times can be realised.

• No coupling relays necessary

The limitatio n of the DC pick-up power is decisive here. The new contactors DIL M – up to 38 A – can be controlled from a PLC by 0.5 A DC outputs.

• Low pick-up and holding power

The PLC outputs are subject to a significantly lower load. The holding power has been minimised. For example a DILM38 requires a holding power of just 0.5 W. It is therefore unnecessary to have to consider the utilisation factor or maximum current carrying capacity

• Twin box terminals provide safety

Simpler mounting: even different conductor cross-sections are now safer to wire

Moeller  produced contactors for the highest currents up to 2000 A.

All the DIL M contactors from 185 A up to 2000 A have electronically controlled drives. You can choose between two available variants: standard and comfort version.

The standard version offers the following benefits for your application with contactors from 185 A to 500 A:

• Significantly less heat rise in the switchgear cabinet due to the sealing consumption being reduced to just 4%
• Long contact lifespan by optimisation of contact forces
• Integrated suppressor for DC actuated contactors
• Auxiliary contacts: 2 NO, 2 NC
• Pricing advantages when standard versions are used

The comfort version offers the following additional benefits for your application with contactors from 185 A to 2000 A:

• Design engineers need to allow only for small control transformers due to reduced pick-up consumption
• Considerably wider voltage tolerance than the Standard demands represents greater reliability in the event of voltage fluctuation
• Direct actuation from PLC possible.

DIL M contactors from 580 A are vacuum contactors that offer considerable advantages over air-break contactors:

• The switching chamber remains absolutely maintenance free for the entire device lifespan.
• The electrical lifespan is significantly longer than with air-break contactors
• It is possible to achieve  a higher packing density and cleaner distribution chamber since no open arcing occurs
