Carling Technologies Expands Circuit Protection with R-Series DIN Rail Breaker

13 mm DIN rail mount hydraulic-magnetic circuit breaker combines maximum protection with ease of use

PLAINVILLE, September 21, 2023 —  Carling Technologies, a Littelfuse, Inc. (NASDAQ: LFUS) brand, announced the introduction of the new R-Series configurable 13 mm DIN rail mount hydraulic-magnetic circuit breaker. Available with up to four poles, the R-Series circuit breaker features no hardware or front panel cutout requirements, an optional rail button, and a choice of 45 mm or 57 mm mounting panels, making DIN rail mounting simple.

Datacom and telecom applications and renewable energy projects require a lot of equipment in increasingly smaller spaces. Our customers are looking for ways to fit more equipment in without sacrificing circuit protection and safety.

The new R-Series circuit breaker has a narrow design, which frees up valuable real estate for revenue-generating devices, and it has recessed wire-ready terminals that are touch-proof and shock-resistant.
