Watlow E-Safe II Hybrid Power Switch
Power Switching at High Ambient Temperatures - NO-ARC Technology
E-SAFE II HYBRID POWER SWITCH

Watlow's patent pending E-Safe II Hybrid Power Switch provides reliable and accurate power switching up to 35 amperes at 70°C (158°F). This mercury-free product is specifically designed to operate in the higher embient temperatures of foodservice applications.

The use of mercury relays is being eliminated due to many regulations affecting its use in the United States and around the world. When replacing mercury-relay switches, the E-Safe II is the best performing product at the most economical price. Because of the product's unique design, there is no need to purchase costly heat sinks used with traditional solid state relays. In addition, this is a three-phase device, so there is no need to wire multiple command signals. With a switching life of millions of cycles and an embient rating of 70°C (158°F), with no heat sink required, this product is more superior than typical SSRs.

The E-Safe II Hybrid Power Switch provides foodservice operators with longer contact life and higher performance than typical mechanical contactors used in equipment. By using Watlow's patent pending NO-ARC technology, the E-Safe II can switch millions of cycles increasing the life of the product with decreased noise and increased temperature accuracy. E-Safe II's inherent ability to operate at fast cycle time provides a nice complimentary product for a time proportioning (PID) controller.

E-Safe II while being mercury free, is also RoHS compliant by design, CE approved and C-UL/UL recognized. The reliability of the product is protected by a 24-month warranty.
