This HEB-series MCCB uses a thermal-magnetic trip to provide both long-time and instantaneous overcurrent protection, with a voltage rating of up to 600 V AC and an interrupting capacity of 65 kA at 480 V, making it suitable for moderate-to-heavy motor loads and feeder protection. The unit is built with load-side lug terminals for secure conductor connections, supports bolt-on mounting, and carries a 40 °C ambient temperature rating, aligning with common industrial installation practices and enabling reliable protection in standard environments. As a Type HEB device, this 3P 100 A breaker is intended for use in compact, modular protective schemes where a field-serviceable bolt-on MCCB is required to protect feeders and motors, while maintaining Siemens’ compatibility with other HEB-series components.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46269097246954,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-019.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/siemens-heb3b100-bolt-on-3-phase-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
