The PTCB E1 24DC/1-8A SI-R is a single-channel electronic fuse tailored for safeguarding 24 V loads. It facilitates straightforward potential distribution with terminal blocks from the CLIPLINE complete system. This unit includes a status output, reset input, and an electronic interlock, and is designed for mounting on DIN rails.

With a rated current adjustable from 1 A to 8 A DC, and a pre-adjusted rated current of 4 A, the device operates within a voltage range of 18 V DC to 30 V DC, making it suitable for various applications. The electronic tripping mechanism ensures rapid response with a shutdown time of ≤ 10 ms for short circuits exceeding 2.0 x IN, while the integrated failsafe element provides additional reliability.

Operating within an ambient temperature range of -30 °C to 60 °C, the circuit breaker maintains high efficiency, exceeding 99%. It also features a maximum capacitive load of 25,000 µF, depending on current settings, and has a notable MTBF of over 24 million hours at 25 °C with 21% load.

This module adheres to several industry standards, including EN 45545-2, and is suitable for railway applications with fire protection requirements for materials and components.
