ABSTRACT

The test object was a ABB Switch disconnector OT200E03. The test was performed in a heating cabinet (NBL2880) at SP Fire Research. The cabinet was set to 200°C prior to the test. The test lasted for 02:09:49 (HH:mm:ss).

The switch disconnector was in closed position during the test.

It is SP Fire Research’s opinion that the tested object meets the criteria for “F200” class stated in EN 12101-3:2002.

Current carrying paths were in good condition with resistance similar to a new unit.

Dielectric test between phases and ground at 1 kV passed.

The test results relate only to the items tested

1 Test specimen

The test object was a ABB Switch disconnector OT200E03. For closer details see

drawing below.

2 Test setup

The test was performed in a heating cabinet (NBL2880) at SP Fire Research. The cabinet

was set to 200°C prior to the test. The test lasted for 02:09:49 (HH:mm:ss). A graphical

presentation of the temperature inside the heating cabinet is presented in Figure 3.

The temperature inside the heating cabinet was monitored by a thermocouple (NBL1304)

of type K (alumel/chromel alloy) with 1.5 mm diameter encapsulation. The thermocouple

was positioned approximately 20 mm from the test object.

The insulation properties were tested with Insulation tester NBL 1362 (Elit 1550 II)

The resistance was measured with digital multimeter NBL 206 (Fluke 8840A) .

The switch disconnector was placed in a steel tray measuring 300 x 300 x 100 mm inside

the cabinet. See Figure 4. Right before initiating the test a steel lid was placed on top of

the tray.

The switch disconnector was in the closed position during the test.

1) The measured resistance increased rapidly after the test. No stable measurement was

found.

2) Maximum resistance on the dielectric tester is 4000 MΩ.

After the heating test the current carrying path was in good condition. The switch

disconnector was partly melted and discoloured. See photos in Section 4 for closer

details.

It is SP Fire Research’s opinion that the tested object meets the criteria for “F200” class

stated in EN 12101-3:2002 Specification for powered smoke and heat exhaust ventilators

(Corrigendum AS:2005 incorporated).
