What is the function of this auxiliary circuit switch?
The auxiliary circuit switch is designed to be used with miniature circuit breakers (MCBs) and residual current operated circuit breakers with overcurrent protection (RCBOs). It provides additional switching capabilities, allowing for remote signalling or interlocking with other devices in an electrical circuit.
Can this auxiliary switch be mounted on any MCB or RCBO?
This auxiliary switch is specifically designed to be mounted on compatible RCBOs and MCBs. It is important to check the compatibility of the switch with the circuit breaker to ensure proper operation.
What type of contacts does this auxiliary switch have?
The auxiliary switch has two normally open (NO) contacts, which means the contacts are open when the switch is in its default position and close when the switch is activated.
What is the voltage type for the control voltage of this auxiliary switch?
The auxiliary switch can operate with both AC and DC control voltages, providing versatility in its application across different electrical systems.
How many pitch units in width does the auxiliary switch occupy?
The auxiliary switch occupies 0.5 pitch units in width, making it a compact addition to an electrical assembly without taking up excessive space.
Is there a specific torque requirement for the terminal connections?
Yes, there is a specified torque requirement for the terminal connections to ensure a secure and reliable connection. It is important to follow the manufacturer's instructions when installing the switch.
What is the temperature range for operating this auxiliary switch?
The auxiliary switch is designed to operate within a specific temperature range, which is typically provided in the technical specifications. Operating outside of this range may affect the performance and longevity of the switch.
