Modular disconnector series BKD 3P 40A BKD 3P 40A

Modular disconnect switch – reliable power disconnection

The BKD 3P 40A series modular disconnect switch is a component used to safely disconnect electrical circuits. It is a key element in electrical installations, providing the ability to switch off the power for maintenance, repair work or in emergency situations. The device is designed for use in both residential and industrial applications.

#### Construction and application

The BKD 3P 40A disconnect switch is designed for mounting on a 35mm wide DIN rail. Its modular construction (width 52.5mm) allows for easy integration with other devices in the distribution board. The three-pole design (3P) allows you to disconnect all phases simultaneously, ensuring complete circuit isolation. The rated current of 40A makes it suitable for protecting circuits with medium power consumption.

This disconnect switch is not an overcurrent circuit breaker – this is an important difference to be aware of during installation. Its only function is to disconnect the circuit, not to protect against overloads or short circuits.

#### Advantages and benefits

* **Safety:** Provides effective circuit disconnection, minimizing the risk of electric shock during maintenance and repair work.

• Durability: Made of high-quality materials, guarantees long and trouble-free operation – withstands at least 1500 electrical operating cycles and 10,000 mechanical cycles.

• Easy installation: Modular design and the ability to mount on a standard DIN rail make installation easier and faster.

• Compliance with standards: Meets the requirements of IEC60947-3 standard, which confirms its safety and reliability.

• Versatility: Suitable for use in various types of electrical installations – both in residential and industrial buildings.

• Rated voltage: Designed to operate at 240/415Vac with a frequency of 50/60Hz.

• Insulation: Has high dielectric strength (600V) and impulse voltage (6kV), which increases safety.

#### Important information for installers

Remember that the BKD 3P 40A disconnect switch *does not replace* an overcurrent circuit breaker! It should be used in conjunction with appropriate protection devices (e.g. automatic circuit breakers) to ensure complete protection of the electrical installation. Installation should be performed by a qualified electrician in accordance with applicable regulations and safety standards. The device is intended for professional use and requires appropriate knowledge and skills during installation and operation.
