Apakah itu geganti beban lampau terma?
A thermal overload relay monitors motor current and operates its control contacts when a sustained overload condition exceeds its time-current characteristics. It is commonly coordinated with a contactor in a motor starter.
An overload relay does not normally provide short-circuit interruption. Its adjustment range, trip behavior, phase sensitivity, reset mode, auxiliary contacts, contactor compatibility and upstream short-circuit protection must be selected together.

Overload Relay Selection Questions
Jawapan pantas untuk perbandingan awal keluarga produk sebelum pengesahan litar terperinci.
What does a thermal overload relay protect against?
It responds to sustained motor overload according to its characteristics and operates the starter control circuit. Exact protection functions vary by model.
Does an overload relay provide short-circuit protection?
Normally no. A coordinated fuse, circuit breaker or motor protective device is required for short-circuit protection.
How is the adjustment range selected?
Choose a relay range that includes the motor nameplate current, then set and commission it according to the motor, starter and product instructions.
What is trip class?
Trip class describes the relay operating-time characteristic under specified overload conditions. The required class depends on the motor starting and protection needs.
Must the relay match the contactor?
Yes. Verify electrical rating, direct-mount or separate-mount compatibility, terminal arrangement and accessory coordination.
