Overcurrent circuit breaker ETIMAT 6 1P B40 002111520

Reliable protection of electrical installations

ETIMAT 6 circuit breaker is an element used to protect electrical circuits against the effects of overloads and short circuits. Designed for use in residential, commercial and industrial installations, it ensures safety and reliable operation. The 1p B40 model is characterized by a rated current of 40A and a tripping characteristic of type B, which means it is ideal for protecting circuits with devices with moderate inrush current.

Construction and application

The ETIMAT 6 circuit breaker is mounted on a TH35 rail and occupies a modular width of 1. Its compact dimensions (installation depth 68 mm) allow for easy installation even in limited space. Designed for durability and reliability, it meets the requirements of IEC/EN 60898-1 and IEC 60947-2 standards. The possibility of connecting wires with a cross-section from 1 to 25 mm² provides flexibility in choosing the appropriate supply wire. The IP20 degree of protection protects against accidental contact and the ingress of solid objects larger than 12.5 mm.

Key features and benefits

• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icn is 6 kA at 230 V and 400 V, which guarantees effective protection of the installation in the event of a short circuit.
• Characteristic B: Provides fast tripping in case of overloads, while allowing for short-term peak loads, typical for devices with motors or transformers. This means that the circuit breaker will not trip unnecessarily during normal operation of the devices.
• Wide operating temperature range: The circuit breaker retains its properties in the temperature range from -25°C to +55°C, which makes it suitable for use in various environmental conditions.
• Versatility: Top or bottom connection possibility and double insulated busbar connection increase installation flexibility and facilitate installation.
• Safety: It has a rated insulation voltage Ui of 500V and withstands impulse voltages of up to 4kV, which further increases safety.
• Expandability: Compatible with ETIMAT 10 auxiliary contacts and DA ETIMAT 10 overcurrent release – extension of functionality if needed.
