The MTL ZoneDefender Curve series surge protectors are specifically designed for applications that require a Type 1 or Type 2 SPD. Type 1 models are available that meet UL96A Master Label Program requirements. This device eliminates the need for additional overcurrent protection providing substantial cost savings. These compact and durable devices offer cost effective, high capacity protection along with application versatility, features which make the range the ultimate surge protection solution.

ZoneDefender Curve units, with a 50kA surge handling capability per phase, provide protection between Line to Neutral, Line to Ground/Earth and Line to Line. Utilizing Metal Oxide Varistor (MOV) technology, the ZoneDefender's protection circuits are highly reliable, dual-redundant varistor networks ensuring your site is never unprotected. Fully automatic in operation, the ZoneDefender Curve reacts immediately, clamping voltage surges without causing undue leakage losses under normal operation. No operator intervention is required, ZoneDefender Curve resets automatically and is maintenance free. Thermal fusing is incorporated into each ZoneDefender Curve as an additional safety feature. Short circuit protection is also supplied, as standard, for added peace of mind.

The ZoneDefender Curve offers an LED Status indication facility allowing each varistor network to be continually monitored and indicated by LEDs on the front panel of the device. The ZoneDefender Curve Series is UL 1449 Listed and boasts an unrivalled 10 year ‘no questions asked' manufacturers product warranty. These devices also exceed the requirements of ANSI/IEEE C62.45 and ANSI/IEEE C62.41.
