ABB 1SYS274012R0404 40 Amp 4 Pole C Curve Miniature Circuit Breaker- SB204 M-C40

Product Description

ABB 40 Amp miniature circuit breaker C curve is a type of electrical protection device designed to automatically switch off electrical circuits in the event of abnormal conditions, such as overcurrent, short circuit, or electrical faults. MCBs are widely used in residential, commercial, and industrial applications to ensure the safety of electrical installations.

Key Features:

• Types of Tripping: MCBs can have different tripping mechanisms, including thermal, magnetic, or a combination of both. Thermal tripping responds to prolonged overcurrent conditions, while magnetic tripping reacts to short-circuit currents.
• Circuit Interruption: When a fault is detected, the MCB opens its contacts, interrupting the electrical circuit and preventing further flow of current. This helps prevent damage to wiring, appliances, and the risk of fire.
• Modular Design: MCBs often have a modular design, allowing them to be easily installed and replaced in standardized electrical distribution panels or consumer units.
• Trip curve: MCBs come in different trip curves, indicating their response time to overcurrent conditions. The choice of trip curve depends on the specific application and the type of load.
• Applications: MCBs are commonly used for protecting lighting circuits, power distribution circuits, and individual electrical appliances. They are a fundamental component in electrical distribution boards and consumer units. It's essential to choose the appropriate MCB rating and type based on the specific requirements of the electrical circuit.
