Three poles, line-protection version, fitted with the ETU340 electronic overcurrent release. The 242 kA breaking capacity at 240 V (187 kA at 415 V, 121 kA at 500 V, 42 kA at 690 V) gives serious fault-interruption headroom for high-available-fault-current installations. That figure drops to 187 kA at 415/440 V and 121 kA at 500 V, still well above typical panel SCCR requirements. At 690 V the 42 kA rating still clears most industrial fault levels. The ETU340 release is adjustable for long-time pickup and short-time delay, letting you coordinate downstream feeders without sacrificing selectivity. Dimensions: 86 mm depth, 105 mm width, 181 mm height. Front IP40 protection keeps dust and accidental contact out of the breaker face. Optional motor drive available for remote tripping or reset.","metaTitle":"Siemens 3VA2125-6HK36-0AA0 SENTRON MCCB, 25 A, 242 kA at 240","metaDescription":"Siemens 3VA2125-6HK36-0AA0 SENTRON molded case circuit breaker, 3-pole, 25 A rated current, 242 kA breaking capacity at 240 V.
