Product Description

A 250A electric circuit breaker is a type of circuit breaker designed to handle electrical currents up to 250 amperes. Here are some key points about this circuit breaker:

Current Rating: The "250A" designation indicates that the circuit breaker is rated to handle a maximum continuous current of 250 amperes. This means it is designed to safely carry electrical loads up to that magnitude without tripping.

Trip Mechanism: Electric circuit breakers utilize various mechanisms to trip and interrupt the current flow in the event of overloads or faults. Depending on the specific type, it could employ thermal, magnetic, or a combination of both to provide reliable protection.

Application: A 250A circuit breaker is commonly used in a range of applications, including residential, commercial, and industrial settings. It can be found in distribution boards, electrical panels, motor control centers, machinery, and other electrical installations where moderate to high currents are present.

Circuit Protection: The primary function of a circuit breaker is to protect the electrical system and connected equipment from excessive current. In the event of an overload or short circuit, the circuit breaker will trip and interrupt the current flow, thereby preventing damage to the wiring and devices.

Types and Configurations: Electric circuit breakers come in various types and configurations, such as miniature circuit breakers (MCBs) for low-current applications, molded case circuit breakers (MCCBs) for higher currents, and air circuit breakers (ACBs) for heavy-duty applications. The specific type of circuit breaker used will depend on factors like the electrical system's requirements, the level of current, and the level of protection needed.

It's important to note that the features and specifications of a particular 250A electric circuit breaker may vary based on the manufacturer and model. It's advisable to consult the manufacturer's documentation or specifications to obtain precise details about a specific product.

RS485 interface,MODBUS-RTU protocol.With MODBUS modul equipped,customers can choose options as below. Remote signal: Switching ON/OFF, tripping, alarm &malfunotional singal indication.

Remote control: Switching ON/OFF,reset.Remote test: 3-phase cuttent &N-pole current, grounding current.Remote adjustment: accept and execute remote command to debug remote control. Tripping unit menory recording function, last three time, tripping records can be well traced.SDM6 circuit breaker also obtains isolation funcion (Can be used as an alternative load switch).

SDM6 molded case circuit breakers (MCCBs) protect cables sized for 100A to 1600 A. Their highest breaking capacities allow them to protect also smaller cables, when connected close to a powerful energy source. As one pillar of digitally connected power distributions (EcoStruxure Power), SDM6 breakers take part in energy consumption and asset management optimization. Benefit from 25 years of technological leadership, and rely on proven quality, opted for even in most demanding environments.

SDM6 circuit breaker complies to GB/T14048.2, IEC60947-2 standards, with CCC.CE, TSE certificate approved.
