Residual current circuit breaker with overcurrent protection KZS-2M A C16/0.03 002173224

Residual Current Breaker with Overcurrent Protection KZS-2M is a reliable and compact device designed to protect electrical installations and people from electric shock. It combines the functions of an overcurrent circuit breaker (protection against overload and short circuit) and a residual current device (RCD), providing comprehensive safety. It is ideal for both new installations and modernization of existing ones.

The design based on characteristic C makes the circuit breaker cope well with shock loads, such as starting motors or compressors – it allows it to react more slowly to short current surges, while ensuring quick operation in the event of an overload or short circuit. The rated differential current of 0.03A (30mA) provides effective protection against electric shock in case of indirect contact. This makes it a suitable solution for residential, office and utility rooms.

Features and benefits:

• Comprehensive safety: Combining overcurrent and residual current protection in one device minimizes the risk of failure and provides a high level of protection.
• Fast reaction: The rated differential current of 0.03A guarantees quick disconnection of the circuit in the event of a leakage current to earth, protecting users from electric shock.
• Resistance to shock loads: Characteristic C allows for trouble-free starting of devices generating high starting currents, such as motors or transformers.
• Easy installation: Compact dimensions (width of 2 modules) facilitate installation on a DIN rail in a switchgear cabinet.
• High quality workmanship: Product of ETI Polam, a renowned manufacturer of electrical equipment, guarantees reliability and durability.
• Versatility of application: Suitable for TN-S, TN-C-S, TT and IT networks.
• Wire cross-section: Possibility to connect wires with a cross-section from 1 to 25 mm², which provides flexibility when selecting supply wires.

The KZS-2M A C16/0.03 circuit breaker has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. The rated short-circuit breaking capacity is 10 kA, which ensures effective disconnection of the circuit in the event of a short circuit. The device operates at a rated voltage of 230V and a frequency of 50 Hz. Thanks to the possibility of sealing the switching lever in the "On" and "Off" positions, accidental change of the circuit breaker state is prevented.
