Seaward PAC3760 Plus II portable appliance and RCD tester

The Seaward PAC3760 Plus II portable appliance and RCD tester is based on the PAC3760 series of portable appliance testers. The Plus II version builds on the range’s features to now include an in-built isolation transformer.

This feature not only eliminates the need to purchase a separate isolation transformer when testing portable RCDs, but also reduces equipment weight as the isolation transformer typically weighs several kilograms.

The tester conducts earth bond, insulation and polarity tests, as well as leakage current tests for Class I and Class II appliances and leads, and carries out trip time tests of 10 and 30 mA portable RCDs. When used in conjunction with the optional PAC-TPL 3 phase adaptor, the Plus II can also carry out 3 phase leakage testing of 10, 16, 20 and 32 A three-phase appliances. The Plus II operates under mains or battery power, providing users with maximum flexibility.

The unit is designed with 6-button operation: Class I, Class II, Leakage, 10 mA RCD, 30 mA RCD and three-phase test buttons. Results are displayed as a pass or fail as well as actual readings. Once the user selects the required test, the tester conducts an automatic sequence of tests, eliminating the need for complicated on-screen menus. Other features include automatic sensing of IEC or extension leads, which adds a polarity test to the sequence and automatic detection of whether the appliance is switched ‘On’.

The tester’s in-built isolation transformer and ability to operate under both battery and mains power make it suitable for manual testing and tagging applications requiring compliance with AS/NZS3760.
