FHL36070 - 70 Amp Circuit Breaker

FHL36070 - 70 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the right match is essential. The goal is usually not to redesign the installation—it is to restore the system with a breaker that fits the original equipment and maintains the intended protection. The Square D FHL36070 is designed for that purpose, providing the correct form, fit, and function for compatible Square D electrical distribution equipment. With a 70 Amp rating, 3-pole configuration, and 600V AC capability, this thermal magnetic molded case circuit breaker is a practical replacement choice for commercial and industrial maintenance applications where compatibility matters.
