TAJ408HD-1 Overview
What is the TAJ408HD-1?
The TAJ408HD-1 is a thermal magnetic circuit breaker used to protect electrical circuits from overloads and short circuits. It is commonly used in residential, commercial, and industrial panels.
Key Features
- Amperage: 40 Amps
- Voltage Rating: 240 Volts
- Type: Thermal Magnetic
- Trip Curve: Type C – ideal for moderate inrush current from motors or lighting
- UL Listed: Compliant with stringent safety standards
How the TAJ408HD-1 Functions
Thermal Protection
The thermal mechanism uses a bimetallic strip that bends with heat from sustained overloads, triggering the breaker to trip.
Magnetic Protection
Responds to immediate surges or short circuits by triggering an instantaneous trip, helping to prevent serious damage.
