A new range of metering units, designed for easy installation on existing supplies or upgrades, helps to provide energy metering to Part L2 of the UK Building Regulations. Havells’ MMU meter management units comprise a multifunction meter in an IP65 enclosure, with pre-wired split-core current transformers. The range comprises 125A and 250A units with standard multi-function meters or MID meters.
To save installation time and risk of errors, the compact split-core CTs are pre-wired to flying leads which are easily connected to the meter terminals. The meters are fully pre-configured for current transformer ratio and voltage. They have in-line fuses to protect the meter and a CT disconnect feature for safe maintenance.
