It carries the ETU550 electronic trip unit, which gives you adjustable overload and short-circuit protection settings rather than fixed thermal-magnetic curves — useful for coordinating downstream breakers or accommodating motor inrush without nuisance trips. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The adjustable current range spans 38 A minimum to 300 A maximum, so the same breaker frame covers multiple tap sizes — a single line-item for the BOM that you set at commissioning. ## Panel fit and communication Front-face protection is IP40, adequate for enclosed switchboards. This variant includes a communication function, which on the 3VA platform typically means a modular communication-capable trip unit that can report status and measured values over a bus — useful for power monitoring without adding a separate meter.","metaTitle":"Siemens 3VA2125-7JP36-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2125-7JP36-0AA0 molded case circuit breaker, 25 A continuous, 3-pole, ETU550 trip unit.
