What is the function of this auxiliary current switch?
The auxiliary current switch is designed to work in conjunction with miniature circuit breakers, such as the 5SL, 5SY, and 5SP series, to provide additional switching capabilities. It allows for remote signalling and control by providing two normally closed (NC) contacts.
Can this switch be used with any miniature circuit breaker?
This switch is specifically designed for use with Siemens 5SL, 5SY, 5SP miniature circuit breakers, as well as the incorporated switch 5TL1, RCBO 5SU1, and FI 5SV. It may not be compatible with other types of circuit breakers.
What are the electrical endurance and mechanical specifications of this switch?
The switch has an electrical endurance of typically 20,000 switching cycles and features a compact design with dimensions of 9 x 70 x 90 mm. It is also rated with an IP20 protection class.
What type of conductors can be connected to this switch?
The switch can accommodate conductor cross-sections ranging from 0.5 mm² to 2.5 mm², and it is suitable for use with AWG conductors sized 24 to 12.
What are the environmental operating conditions for this switch?
The switch can operate within an ambient temperature range of -25 °C to +55 °C and can be stored in temperatures ranging from -40 °C to +75 °C.
How is the switch mounted to a circuit breaker?
