Isolating switch Dumeco 4P 160A DMV-160N/4 1814179

Insulation disconnect switch – safety and reliability in one

The Dumeco DMV-160N/4 insulation disconnect switch is a robust device designed for safely disconnecting electrical circuits. It provides a visible isolation gap, guaranteeing complete safety during installation maintenance and repairs. This is particularly important for installers who need to be sure that the circuit is completely isolated before starting work. The device is an alternative to compact disconnectors when there is no need to use additional accessories.

### Design and application

The DMV-160N/4 disconnect switch is characterized by a very small mounting depth, which makes it easy to install even in limited spaces. It is designed for mounting on a plate and in distribution boards. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Its construction – a complete device in a housing – minimizes installation time and ensures readiness for operation immediately after mounting. It can function as a main, repair, or emergency disconnector.

### Key features and benefits

* **High switching capacity:** Rated operating power for AC-23, 400 V is 90 kW, and the rated continuous current Iu is 160 A – ideal for demanding industrial and commercial applications.

* **Safety first:** Visible isolation gap guarantees complete circuit isolation during maintenance and repair work.

* **Compact dimensions:** Width 158 mm, height 122 mm and depth of only 59 mm allow for mounting in tight spaces.

* **Versatility:** Can be used as a main, repair or emergency disconnector.

* **Durability and reliability:** Made of high-quality materials ensuring long-lasting trouble-free operation.

* **Easy installation:** Complete device in a housing minimizes installation time.

* **Short-circuit protection:** Rated conditional short-circuit current Iq is as high as 100 kA, providing effective protection of the installation against the effects of short circuits.

* **Screw connection:** Provides a secure and durable connection of wires.

### Technical parameters in practice

The DMV-160N/4 disconnect switch has been designed with demanding electrical applications in mind. Its rated operating voltage (690…690 V) and high ability to withstand short-circuit currents (8 kA) guarantee safe and reliable operation in various operating conditions. C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. It protects the circuit against overload and short circuit — like most circuit breakers in this class. Protection class IP20 provides protection against accidental contact, but does not protect against the influence of water or dust – remember about appropriate environmental conditions during operation of the device.
