IDEC Protection Relays
Protect motors from thermal overload and damage caused by overloads, phase loss and overcurrent with IDEC thermal overload relays. These relays are widely used in motor control circuits, control panels and OEM equipment where space is limited and reliable motor protection is required. IDEC thermal overload relays offer reliable protection to help extend motor life and reduce costly downtime.
Common applications for these relays include motor starters for pumps, fans, conveyors, compressors and general purpose industrial motors. They are often used in conjunction with contactors in a motor starter. Thermal overload relays monitor motor current and trip when the current exceeds a predetermined level for a given amount of time. The thermal response of the relay mimics the heating characteristics of the motor allowing the relay to trip the motor off before damage to the motor insulation or mechanical components occurs.
FAQs
What is an IDEC thermal overload relay used for?
An IDEC thermal overload relay is used to protect electric motors from overheating caused by overload, phase loss, or excessive current. It is commonly installed in motor starters, control panels, and industrial automation systems to prevent motor damage and downtime.
How does an IDEC thermal overload relay work?
IDEC thermal overload relays work by monitoring motor current and simulating motor heating characteristics. When 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.
What applications use IDEC thermal overload relays?
IDEC thermal overload relays are commonly used in pumps, fans, conveyors, compressors, material handling equipment, and general-purpose industrial motors in manufacturing and automation environments.
Are IDEC thermal overload relays used with contactors?
Yes, IDEC thermal overload relays are typically used in combination with contactors as part of a motor starter. When an overload condition occurs, the relay trips and signals the contactor to disconnect power to the motor.
Are IDEC thermal overload relays suitable for control panels and OEM equipment?
Yes, IDEC thermal overload relays are designed for control panels and OEM equipment. They offer compact designs, adjustable current ranges, reset options, and compatibility with industrial control voltages.
Why choose IDEC thermal overload relays over other brands?
Engineers choose IDEC thermal overload relays for their compact size, accurate motor protection, reliable trip characteristics, and long service life in industrial automation and motor control applications.
