Product Identification

Important: the attached product is an RCBO, not an ordinary MCB. It combines residual-current (earth-leakage), overload and short-circuit protection.

Short Description

The TOMZN TOB1L-63H C32 is a 32A, 2-pole AC RCBO designed to disconnect both line and neutral while providing 30mA earth-leakage, overload and short-circuit protection. The supplied unit is marked for 230V AC, 50/60Hz operation, a 6kA breaking capacity and IEC 61009-1 compliance.

Long Description

Protect residential AC circuits with one compact device. The TOMZN TOB1L-63H C32 combines overcurrent and residual-current protection, helping guard wiring against overloads and short circuits while responding to sinusoidal alternating earth-fault currents.

This 32A variant is rated for 230V AC at 50/60Hz and disconnects both L and N. Its 30mA residual-current sensitivity, yellow test button, linked blue operating toggle and visible status window make routine operation and functional testing straightforward. The product label identifies a 6kA breaking capacity, Type AC residual-current marking and IEC 61009-1 standard.

The unit is intended for correctly designed residential distribution circuits. Selection, wiring and installation must be completed by a qualified electrician in accordance with local electrical regulations and the official wiring information for the product.
