Moeller Control Indication T Rotary Switches & P Switch disconnector
Overview
Tailor-made solution for any task
T rotary switches and P switch-disconnectors are also available for a wide range of different standard circuits and ratings.
Even the number of possible switch combinations is virtually unlimited.
Different designs, front plates and special switches ensure optimum flexibility to meet the requirements at hand.
Furthermore, application safety is always the prime consideration in design. The covered terminals are finger-proof to VDE 0106.
Typical applications for T rotary switches and P switch-disconnectors include:
- Maintenance, repair and safety switches
- On/Off switches
- Main switches
- Control switches
- Panic switches
- Manual/automatic switches etc.
P1, P3 and P5 Switch Disconnectors up to 315 A
Like rotary switches, P switch disconnectors are manually operated switching devices without any release or switch mechanism but with a direct link between manual operating element and the contact. The contacts are positively opened on de-energization, and the auxiliary contacts are interlocked opposing contacts.
Switchable "N conductors" and/or "HI21 auxiliary contacts" can be connected to the P1, P3, or P5 switch disconnector with a make and break contact. The auxiliary make contact is always switched as a load shedding contact for control of the contactor. In this manner, the contactor assumes the switching task and the switch-disconnector only needs to disconnect the main current circuit
Typical application for P switch disconnectors, e.g:
Maintenance, repair and safety switch
P switch disconnectors are particularly suitable as safe maintenance and repair switches or as enclosed main switches for individual electrical loads.
Multiple padlocks can be connected in the OFF position. This provides a vital safety function: the no-voltage state is visible and switch on is impossible.
ON/OFF switch
P switch disconnectors provide reliable operation with heating and lighting systems, motors, etc. They are also suited for direct switching of motors. Selection of the switch is performed to suit the rated uninterrupted current or the motor rating in accordance with utilization category AC-23A. In applications where frequent switch on and off operations are necessary, the high switching capacity guarantees reliability.
Atex T rotary switches and P switch-disconnector up to 100 A
