Must Have Siemens / ITE HE3A005 – 5A 3 Pole Motor Circuit Protector

Designed exclusively for motor branch circuits, this 5A instantaneous-trip protector clears faults up to 65kA at 240V. It mounts securely into vintage ITE and Siemens motor control centers, offering a precise physical match for aging infrastructure. Maintenance teams rely on this specific E-frame profile to restore equipment without modifying existing buswork. While the ED63A005 is the modern substitute, this legacy component ensures immediate compatibility for older systems.
