Part Number F3B003M is your reassurance that you’re sourcing an authentic, compatible component for Siemens panels and control gear.\u003c\/p\u003e \u003cp\u003eDesigned for simultaneous phase protection, this 3-pole breaker ensures all three phases trip together in the event of an overload or fault. That coordinated disconnection helps safeguard motors, drives, and other three-phase equipment, reducing the risk of unbalanced loads and equipment damage in industrial and commercial applications. The 3 A current rating provides a precise trip threshold ideal for control circuits, automation panels, and low-load feeders where stability and predictable behavior matter.\u003c\/p\u003e \u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eCurrent rating: 3 A\u003c\/li\u003e \u003cli\u003ePoles: 3 for three-phase protection\u003c\/li\u003e \u003cli\u003eVoltage rating: 480 V, suitable for common industrial three-phase systems\u003c\/li\u003e \u003cli\u003ePart Number: F3B003M, an authentic Siemens replacement\u003c\/li\u003e \u003cli\u003eDesigned for reliable operation within compatible Siemens panels and enclosures\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eProtection for 3-phase equipment in manufacturing lines, conveyors, and machine control panels\u003c\/li\u003e \u003cli\u003eReplacement part in upgraded or legacy Siemens distribution boards\u003c\/li\u003e \u003cli\u003eSmall-draw control circuits and feeders where precise trip behavior is critical\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy choose the Siemens F3B003M?\u003c\/h3\u003e\n\u003cp\u003eAuthentic Siemens engineering translates to consistent trip characteristics, robust mechanical action, and availability in standard replacement parts channels. With its 3-pole configuration and 480 V rating, it’s a practical solution for keeping three-phase systems safe without over-tripping during normal operation. This makes it a smart, long-term investment for maintaining reliability in industrial controls and commercial electrical infrastructure.\u003c\/p\u003e \u003cp\u003eCompatibility and installation tip: verify that your panel or distribution board is designed for 3-pole devices at 480 V and that the form factor matches the F3B003M. If you’re replacing an existing unit, this part serves as a straightforward, drop-in replacement to restore intended protection quickly and with minimal downtime.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46423261675682,"sku":"F3B003M","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\/siemens-f3b003m","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
