The nut keeper kit on this variant secures the breaker in a DC Power OEM cabinet built in China; the 100% N conductor protection means the neutral pole is switched and protected identically to the phase poles, critical for 4-wire systems where an open neutral can float voltages.","metaTitle":"Siemens 3VA1140-5GF42-0AA0-ZD00 Circuit Breaker, 40A, 55kA","metaDescription":"Siemens 3VA1140-5GF42-0AA0-ZD00 IEC frame 160 circuit breaker, 40A TM240, 55kA @ 415V.
