IDEC Protection Relays

Thermal overload relay with adjustable current setting dial, manual/automatic reset selector, test button, and screw terminals, designed for motor overload protection in industrial control panels.

IDEC Thermal Overload Relays provide dependable motor overload protection in industrial control panels, motor starters, and OEM equipment. Designed to protect electric motors from overheating caused by sustained overloads, phase loss, or overcurrent conditions, these relays help reduce the risk of insulation damage and premature motor failure. Their compact footprint makes them well-suited for space-constrained panels and machine-mounted control enclosures.

Commonly installed in conjunction with contactors as part of a motor starter assembly, IDEC thermal overload relays monitor motor current and respond when it exceeds a preset value for a defined period. The relay’s thermal response curve is designed to approximate the heating characteristics of the motor, allowing it to trip before damage occurs while minimizing nuisance shutdowns during normal inrush or startup conditions.

These relays are widely used in applications such as pumps, fans, conveyors, compressors, and general-purpose industrial motors. With adjustable current settings and reset options (manual or automatic, depending on model), IDEC thermal overload relays support flexible integration into manufacturing, automation, and material handling systems where reliable motor protection is essential.

FAQs

Q: What is an IDEC thermal overload relay used for?
An IDEC thermal overload relay protects electric motors from overheating caused by overload, phase loss, or excessive current. It is typically installed in motor starters and control panels to help prevent motor damage and downtime.

Q: How does an IDEC thermal overload relay work?
The relay monitors motor current and simulates the motor’s thermal characteristics. If the current exceeds the preset overload setting for a sustained period, the relay trips and opens the control circuit to shut down the motor before damage occurs.

Q: What applications use IDEC thermal overload relays?
They are commonly used with pumps, fans, conveyors, compressors, and other industrial motors in manufacturing, automation, and material handling environments.

Q: Are IDEC thermal overload relays used with contactors?
Yes. IDEC thermal overload relays are typically paired with contactors in a motor starter configuration. When an overload condition is detected, the relay trips and signals the contactor to disconnect power to the motor.

Q: Are IDEC thermal overload relays suitable for control panels and OEM equipment?
Yes. IDEC thermal overload relays are designed for panel integration and OEM use, offering compact construction, adjustable current ranges, and compatibility with common industrial control circuits.

Q: Why choose IDEC thermal overload relays?
IDEC thermal overload relays are specified for their compact size, accurate trip characteristics, and dependable performance in industrial motor control applications.
