Overview
The S 6600H, S 6600U and KT 6680U are universal safety testers designed for comprehensive electrical safety testing in laboratories, workshops and production environments. The S 6600H and S 6600U are modern desktop devices; the KT 6680U is a rack-mount plug-in module.

Connections & variants

• S 6600H: desktop unit with country-specific mains sockets on the front panel for direct device connection.
• S 6600U: desktop unit with laboratory sockets and high-voltage sockets on the front panel for versatile test setups.
• KT 6680U: plug-in rack unit for integration into existing test racks and automated test systems.

Key test functions

• High-voltage (Hipot) test AC: 100 – 5,500 V, test current up to 20 mA.
• High-voltage (Hipot) test DC: 100 – 6,000 V, test current up to 20 mA.
• Insulation measurement (DC): test voltage 100 – 6,000 V; resistance range stated: 100 kΩ – 50 GΩ (alternative reference: 250 kΩ – 50 GΩ).
• Ground bond (protective conductor) test AC: 1 – 32 A; resistance range 0 – 6 Ω.
• Resistance measurement: 1 Ω – 1 MΩ.
• Continuity thresholds: < 14 Ω = short circuit; > 100 kΩ = no continuity.

Applications

• End-of-line and production safety testing for appliances and components.
• Quality assurance in electronics and electrical manufacturing.
• Laboratory safety verifications and service/repair testing.
• Tests for medical devices, power electronics and e-mobility components (where function tests are not required).

Details
The devices focus on safety-related measurements: AC/DC hipot, insulation resistance and ground bond testing. The high-voltage ranges support AC tests up to 5,500 V and DC up to 6,000 V with test currents up to 20 mA. Insulation measurement covers very high resistance values suitable for assessing insulation quality. Ground bond testing provides currents from 1 A to 32 A for protective conductor verification. Connection options depend on the variant selected (front-panel mains sockets, laboratory/HV sockets or rack integration).
