Installation Instructions
◇The sensor assembly is pre-integrated into the circuit breaker pole; ensure the pole is correctly installed in the breaker body.
◇The matching power supply device (energy-taking companion) must be installed inside the circuit breaker box as per design.
◇During ordering, provide the manufacturer with detailed specifications: rated voltage/current transformation ratios, single-pole supply voltage and power (2-5W range), and the designated power supply phase sequence.
◇For any special requirements, contact the manufacturer directly to arrange customization prior to installation.
