Tri-Load Distribution Boards

2 / 2

With an ever increasing focus on the cost of energy, understanding energy consumption is a key element of the building regulations. Havells have
a variety of integrated metering solutions for electrical distribution boards including the unique Tri-Load board.
Tri-load is the only standard distribution board that conveniently separates small power circuits, lighting circuits and mechanical services loads and
provides net energy values of each load type. Tri-load is supplied fully configured and ready to go with the main switch pre-installed. Where required,
the board can be easily set up as a power and lighting only board. In this mode, two TP outgoing ways are added to either the lighting or Power
section, creating additional flexibility in application.
The metering meets the requirements of IEC 62503-21 Class 1.
All Tri-load Distribution Boards are supplied fitted with 200A CBI Circuit Breaker Switch ready for supply cables. For a single phase incoming supply
a single phasing kit (PSBTL1NK) is available to facilitate easy conversion of the pre-fitted circuit breaker switch.
Note: The Triload energy meter is configured to TPN mode as standard but can be easily configured to SPN mode during installation as indicated
in the supplied installation manual.

As part of the Tri-load range, Triload renewable
delivers a uniquely convenient and cost effective
management of building services end loads,
including the renewable content.
It provides visual and remote collection of data
for energy monitoring of Power, Lighting circuits
and the generated supplies from PV / wind etc,
in a standard MCB board design.
