Motor starter, 3-phase, type MMS-32H with a range of 11-17A MMS-32H 17A

3-Phase Motor Starter MMS-32H – Reliable Motor Protection

This MMS-32H 3-phase motor starter is a key element in protecting induction motors. Designed to operate in the 11-17A range, it effectively protects against short circuits, overloads, and phase imbalance. Its solid construction and precise operation ensure long-term and trouble-free operation in demanding industrial conditions.

Functionality and Application

The MMS-32H starter is designed to switch on and protect induction motors with a nominal current of up to 32A. Thanks to its phase failure sensitivity, it minimizes the risk of damage caused by the absence of one of the supply phases. The ability to use it to protect motors powered from a single-phase network (with appropriate phase connection) increases its versatility. Equipped with a knob, it provides convenient operation and precise settings.

Characteristics and Benefits

• Versatile application: ideal for protecting 3-phase induction motors, and also – with appropriate connection – single-phase motors.
• Overload and short-circuit protection: provides effective protection of the motor against damage caused by excessive load or a short circuit in the circuit.
• Phase failure sensitivity: protects the motor against operation in conditions of voltage asymmetry, which extends its service life.
• Solid construction: complete device in a housing with dimensions of 45 x 105 x 90 mm guarantees durability and resistance to mechanical damage.
• Precise settings: the setting range of the overload release (11-17A) allows you to adapt the protection to specific application needs.
• IP20 protection class: provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Thermal protection: additionally protects the motor against overheating, which is particularly important during long-term operation under load.
