A Rational 40.02.425P Varistor/Surge Protector shields internal components from voltage spikes for steadier performance and dependable control.
The varistor/surge protector absorbs and diverts damaging voltage spikes away from sensitive oven or steamer electrical components so the equipment can operate reliably. Its construction is important because it is designed for 208/240V applications and must react quickly to transient surges that could otherwise damage controls, boards or other circuits.
The varistor/surge protector may be nearing replacement if the equipment experiences intermittent electrical faults, unexpected shutdowns or reduced protection after power fluctuations. Physical signs can include scorching, cracking, discoloration or a burnt odor and environmental signs may include repeated exposure to power surges, unstable incoming voltage, heat or moisture that can accelerate wear.
