Special version 3500-...-2350
Typical applications
Single pole thermal-magnetic circuit breaker suitable for high ambient
temperatures. The special rating of the circuit breaker allows resetting
at no load in ambient temperatures up to +80 °C.
Suffix -2350 is also available for types 3400 and 3600.
