The breaker is rated for any mounting position and any supply cord position, so orientation in a crowded enclosure isn't a constraint. The breaker carries approvals to IEC / EN 60898-1 and IEC / EN 60947-2 / UL1077, which covers most industrial control panels in North America and Europe. It's halogen-free and silicon-free — a requirement in clean-room or high-reliability environments where outgassing can contaminate contacts or optics. ## Panel integration The breaker is sealable, which lets a panel builder lock the toggle position after commissioning to prevent unauthorized reset. Ambient humidity derating applies: 95 % RH up to 55 °C, dropping to 35 % RH at 75 °C.","metaTitle":"Siemens 5SY7302-7 SENTRON MCB, 3P C-Curve 2A, 15/50 kA","metaDescription":"Siemens 5SY7302-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 2 A rated.
