At United Force Trading Company, a trusted Schneider Retail Partner, Contactors and Overload Relays form a critical duo in low voltage (LV) power systems, enabling safe and efficient control of motors and electrical loads. These components work together to automate operations, protect equipment from damage, and ensure reliable performance across industrial, commercial, and infrastructure applications.

Contactors

Function: Electromechanical switches that remotely control power circuits, enabling the start/stop of motors, lighting, and other high-power loads.
Operation: Activated by a low-voltage control signal (e.g., from a PLC or push button). The electromagnetic coil opens or closes the main contacts to control power flow.

Overload Relays

Function: Protect motors from overheating caused by prolonged overcurrent conditions such as mechanical jams or voltage imbalance.
Operation: Continuously monitor motor current and trip when preset limits are exceeded, disconnecting power through the associated contactor.

Key Features of Contractors & Overloads

High Switching Capacity: Handle frequent switching operations without excessive wear.
Modular Design: Supports auxiliary contacts, timers, and surge suppressors.
Versatility: Suitable for AC/DC circuits and a wide range of load types.
Adjustable Trip Settings: Calibrated to match motor full-load current (FLC).
Reset Options: Manual or automatic reset after thermal cooldown.
Phase Loss Protection: Detects phase imbalance or loss to prevent motor damage.
