Motor starter MS116-2.5A 1SAM250000R1007

Motor protection circuit breakers – reliable protection for your motors

This MS116-2.5A motor protection circuit breaker is a compact and economical solution for protecting motors up to 0.75 kW (at 400V). The device combines thermal and overload protection, providing comprehensive protection against damage. A width of only 45 mm allows for efficient use of space in the switchgear cabinet.

The MS116-2.5A circuit breaker is designed for both three-phase and single-phase installations, making it a versatile choice for a wide range of applications. It features a built-in disconnecting function, temperature compensation and a free-release mechanism, which translates to reliability and precision. Clear markings on the knob make it easy to read the device status and quickly identify any problems.

• Versatility: Suitable for three- and single-phase installations.
• Compact size: 45 mm width makes it easy to install in tight spaces.
• Thermal and overload protection: Protects the motor from damage caused by overheating or overload.
• High short-circuit breaking capacity: Ensures safe disconnection of the circuit in the event of a short circuit (75 kA at 400V).
• Temperature compensation: Maintains stable operating characteristics in different temperature conditions.
• Easy operation: Knob with clear switch position indication makes it easy to identify the device status.
• Expandability: Compatible with additional auxiliary contacts, signaling contacts and undervoltage releases (available separately).

The MS116-2.5A is characterized by an overload release setting range of 1.6 to 2.5 A, allowing for precise adjustment to the load characteristics. The rated continuous current is 2.5 A, and the rated operating voltage is 690 V AC. The device meets safety standards and has a protection class of IP20, providing protection against accidental contact. Mounting is on a TH rail, which facilitates installation and replacement of the device. Screw connections ensure a secure and durable connection of conductors with a cross-section from 1/2x2.5 mm² to 6 mm². Phase failure sensitivity further increases the safety of the protected motor.
