Circuit breaker for transformer protection 16A PKZM0-16-T 088917

Transformer protection circuit breaker – reliability and installation safety

This three-pole transformer protective circuit breaker, designated as PKZM0-16-T and with a rated current of 16A, is a key element ensuring effective protection in electrical installations. Designed in accordance with IEC/EN 60947, it offers reliable protection against overload and short circuit, as well as protects against the effects of phase failure. It is an ideal solution for both professional installers and end-users looking for solid and safe protection.

Design and application

The PKZM0-16-T circuit breaker is characterized by a solid, fixed mounting design, which guarantees stable operation even in difficult conditions. It is designed for mounting on a TH rail, and its versatility allows it to be used in a wide range of installations – from control circuits to low-voltage switchboards. Screw terminals ensure secure and durable connection of wires. The rated operating voltage of up to 690V AC makes it suitable for various industrial and commercial applications.

Advantages and benefits

• Versatility: Ideal for protecting single-phase and three-phase transformers with a voltage of up to 690V AC.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icu at 400 V, 50 Hz is as high as 50 kA, which ensures effective protection in the event of a short circuit.
• Current adjustment: The setting range of the overload release (10-16A) allows for precise adjustment to the load characteristics.
• Safety: The built-in short-circuit release with a setting range of 358A provides a quick response in the event of an overload or short circuit.
• Trip indicator: Allows for quick identification of the cause of the circuit breaker operation – overload or short circuit.
• Durability: Made of high-quality materials, ensuring long life and reliable operation. Protection class IP20 protects against contact and provides basic protection against solid objects.
• Compatibility: Compliant with IEC 60947-4-1 and VDE 0660 standards, which guarantees safety and compliance with applicable regulations.
• Space saving: Compact design allows for optimal use of space in the switchboard.
• Resistance to inrush currents: Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.

The PKZM0-16-T circuit breaker is an investment in the safety and reliability of your electrical installation. It protects the circuit against overload and short circuit — just like most circuit breakers in this class.
