ABB OTE16T3M Three Phase Thermal Overload Relay

ABB OTE16T3M is a three-pole, plastic-enclosed EMC safety switch designed to provide safe isolation of 3-phase motors in industrial control panels. Rated for 16 A at 400 V AC, with IP65 ingress protection, its robust enclosure resists dust and water ingress in demanding workshop environments. The unit features three-pole screw-terminal connections for straightforward wiring and includes a single normally open auxiliary contact to support interlocking and status signaling in automation circuits. This enclosure-type switch is commonly employed for motor protection in conveyors, pumps, fans, and processing equipment where reliable disconnection of power is required. With a motor rating up to 7.5 kW at 400 V, the OTE16T3M delivers a compact, reliable solution that aligns with typical machine-safety practices and integrates with other ABB protection and switching devices within a control architecture. Its EMC designation helps minimize interference in nearby control electronics, making it suitable for panel-mounted installations in manufacturing, building services, or industrial automation setups where certified isolation and clear visual indication of OFF status are essential.
