Description Siemens 3VA The auxiliary and alarm switches for auxiliary contacts and undervoltage release 3VA molded box circuit breakers can be installed in all sizes of circuit breakers, up to 630 A. All auxiliary and alarm switches are designed as transfer contacts, providing high flexibility for planning and installation purposes. Auxiliary switches send molded box circuit breaker main contact position signals (RS 874-4534 and 874-4537) and trip alarm switches send each circuit breaker trip signal, regardless of the reason for the trip (RS 874-4512 and 874-4515). After the molded box circuit breaker main contact is opened by the ETU, the electrical alarm switch operates (RS 874-4519). The short-circuit alarm switch signal only trips when opened by a short circuit (RS 874-4528).) Under voltage release can trip the molded box circuit breaker in the event of a rated voltage fault or a drop to between 70% and 35% of the normal value (compatible with relevant standards). Provide devices with rated voltage in the following range: 230 V AC (RS 874-4525) 24 V DC (RS 874-4521) STL type parallel trip can be installed in the left accessory compartment as an alternative to undervoltage release. Provide devices with 5 rated voltages in the following range: 230 V AC (RS 874-4540) 24 V AC/DC (RS 874-4531) # # # Siemens 3VA MCCB # # Siemens 3VA MCCB and accessories
