Selective 3P circuit breaker E 80A TS35 HTN380E

Selective overcurrent circuit breakers – protection and reliability in one

This three-pole selective overcurrent circuit breaker, with a rated current of 80A, is a key element in protecting the electrical installation. Designed for mounting on a DIN rail (TS35), it provides effective protection against overloads and short circuits, minimizing the risk of failures and fires. The E tripping characteristic makes it ideal for circuits with devices with high inrush currents, such as motors or transformers.

Safety and functionality for professionals and users

The HTN380E circuit breaker is characterized by a high breaking capacity of 25kA at 400V, which guarantees its reliable operation even in difficult conditions. The three-pole design provides full protection of the entire circuit. Compliance with safety standards (rated insulation voltage Ui 690V, protection class IP20) confirms its high quality and safety of use. Thanks to selectivity, in the event of a failure, it only disconnects the damaged part of the installation, allowing the remaining circuits to continue working – this saves time and repair costs.

Key features and applications

• Selectivity: In the event of a short circuit, it only disconnects the damaged circuit, without interrupting the power supply to the rest of the installation. This is particularly important in residential and commercial buildings where continuity of supply is key.
• E characteristic: Adapted to protect circuits with devices generating high inrush currents during start-up (e.g. motors, transformers). Allows to avoid unnecessary tripping of the circuit breaker during normal operation of devices.
• DIN rail mounting: Enables quick and easy mounting in electrical switchboards. TS35 standard ensures compatibility with most switchboards available on the market.
• High breaking capacity: 25kA at 400V guarantees effective interruption of a short circuit even at high currents.
• Three-pole design: Provides comprehensive protection of the entire circuit.
• Application: Ideal for protecting lighting circuits, socket outlets and electrical devices requiring protection against overloads and short circuits in residential, commercial and industrial buildings.
• Protection degree IP20: Means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside switchboards.

The HTN380E circuit breaker is a solid and reliable solution for every installer and user looking for safe and effective protection of their electrical installation.
