Selective three-pole circuit breaker E 16A TS35 HTN316E

Selective overcurrent switch – protection and reliability of the installation

This three-pole overcurrent switch with characteristic E is a key element of every safe and reliable electrical installation. Designed for mounting on a DIN rail, it provides effective protection of circuits against overload and short circuit. Its selectivity allows for precise operation in the event of a failure, minimizing the risk of unnecessary shutdown of the entire installation.

Functionality and parameters

The HTN316E switch operates at a frequency of 50 Hz and a rated voltage of 400 V, and its rated current is 16 A. The tripping characteristic E means that the switch reacts more slowly to short current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents. The rated switching capacity of 25 kA guarantees effective circuit interruption in the event of a short circuit.

The construction of the switch meets the requirements of overvoltage category 4 and pollution degree 3, making it suitable for use in various industrial and commercial environments. The rated impulse withstand voltage is 6 kV, and the rated insulation voltage Ui is 690 V. The IP20 degree of protection provides basic protection against contact and ingress of solid objects.

Installation and application

Mounting on a DIN rail is quick and easy, which translates into time savings during installation. This switch is used to protect lighting circuits, socket outlets and other electrical devices requiring protection against overload and short circuit. It is ideal for both professional installers and end customers looking for a reliable solution to protect their electrical installation. The ability to connect wires with a cross-section from 1.5 mm² to 50 mm² (rigid) or from 1.5 mm² to 35 mm² (flexible) ensures wide compatibility with various types of wires.
