Features
• Fusible resistors are triggered instantly on contact with mains voltage (230Veff), without flame or explosion.
• The resistor wire is wound around a capped ceramic carrier and fused to the caps.
• In case of vaporisation of the wire, a special varnish absorbs the metal vapour and prevents arcing and consequent short circuit.
• The winding wire is dimensioned in such a way that, for all resistance values between 10R and 330R (100R for the 251-4 model), vaporisation occurs with mains voltage.
• The resistor elements are encased in a silicon varnish and, in the classic sense, are not electrically insulated.
• For resistance values under 10R as well as for other voltages, it has been ensured that the resistor is flame retardant.
• The triggering function, however, has to be tested on an individual basis.
