ABB 87TS50E-E GKWE857800R1214

Product Introduction

ABB 87TS50E-E is a thermal overload relay under ABB, belonging to the TS series protection device, usually used in conjunction with ABB contactors to provide overload and phase loss protection for motors.

Product Description

Core Functions

Overload protection: ABB 87TS50E-E GKWE857800R1214 detects current through a bimetallic thermistor. When the motor current exceeds the set value or runs in an overload state for a long time, it triggers a trip.

Phase loss protection: Automatically cut off the circuit when the three-phase power supply is missing a phase to prevent motor damage.

Manual/automatic reset: ABB 87TS50E-E GKWE857800R1214 supports users to select reset mode to adapt to different application scenarios.

Key Parameters

Rated current: 50A.

Working voltage: Suitable for low-voltage systems.

Trip level: Usually Class 10 (trip within 10 seconds), which meets the motor starting characteristics.

Environmental adaptability: -20°C to +60°C, protection grade IP20.

Compatibility

Modular installation with ABB A series contactors saves space.
