Selective circuit breaker 3P E 63A TS35 HTN363E

Selective overcurrent circuit breaker – protection and reliability of the installation

This three-pole selective overcurrent circuit breaker, with a rated current of 63A, is a key element in protecting the electrical installation. Designed for mounting on a DIN rail, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. The E characteristic makes it particularly well suited for circuits with receivers generating high inrush currents, such as motors or transformers.

Construction and application

The HTN363E circuit breaker is a component intended for both residential and commercial installations. Its selectivity means that in the event of a short circuit, only the circuit breaker closest to the fault location will trip, while the remaining circuits remain energized. This is important for maintaining the continuity of power supply to critical points in the installation. The rated switching capacity of 25 kA guarantees effective circuit interruption in the event of high short-circuit currents.

• Mounting: Easy mounting on a standard DIN rail (TS35) allows for quick integration with existing electrical infrastructure.
• Application: Ideal for protecting circuits with high power demand, such as kitchens, workshops or server rooms.
• E characteristic: Provides delayed tripping with short-term overloads, which is particularly important for devices with induction motors or transformers.
• Safety: Meets the required safety standards (rated insulation voltage Ui 690V, protection degree IP20), ensuring safe operation.
• Durability: Made of high-quality materials guarantees long life and reliable operation even in difficult working conditions (operating temperature -25°C to +55°C).

Key parameters and benefits

The HTN363E circuit breaker stands out with a number of technical parameters affecting its performance and reliability:

A rated current of 63A provides effective protection for circuits with high power consumption. The E characteristic protects devices generating high inrush currents, and the switching capacity of 25 kA guarantees a quick circuit interruption in the event of a short circuit. The rated insulation voltage Ui of 690V ensures a high level of safety. The three-pole design allows for the protection of three-phase electrical circuits, and mounting on a DIN rail facilitates and speeds up installation.

Thanks to the combination of these parameters, the HTN363E circuit breaker is a comprehensive solution for professionals and end users looking for reliable protection of the electrical installation. Its selectivity allows for precise fault location and minimizes downtime in the electrical system.
