It’s designed to withstand the demands of continuous operation in manufacturing floors, data centers, and utilities-grade facilities. Its three-pole configuration ensures synchronized protection across all phases, reducing the risk of unbalanced faults and equipment damage. When integrated into proper protection schemes and paired with compatible monitoring approaches, it contributes to safer, more efficient power management.\u003c\/p\u003e \u003cp\u003ePractical notes: verify compatibility with your existing switchgear and wiring practices, and use the same part number to preserve protective characteristics. This unit is well-suited as the main protective device in 3-phase 600 V systems and is a solid replacement option for HM3-series installations.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Industrial","offers":[{"title":"Default Title","offer_id":46423082959010,"sku":"HM3B500","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/industrial-hm3b500","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
