                  NEMA 12 circuit breaker enclosures deliver dust-tight, drip-resistant protection for manufacturing facilities, processing plants, and OEM equipment. Designed for harsh indoor environments, each enclosure is CSA C22.2 and UL 489 approved and compatible with Noark Ex9 M-Series MCCBs (15 A – 600 A).
                  These heavy-gauge steel housings prevent ingress of dirt, lint, and oil, making them ideal for industrial control panels and machinery disconnects. With padlockable covers and pre-punched conduit entries, installation is fast, safe, and compliant with Canadian standards.
