Electrical Speciﬁcations by Items

Schedule of limitations:

1) The fuse must be so mounted that creepage and clearance distances aren’t impaired in any way.

2) The fuse is suitable for use in intrinsically safe equipment for voltages not exceeding 190V peak.

3) Maximum surface temperature rise at 170% rated current ≤750mA=40ºC, 1A=55ºC, 3A=118ºC and 5A=135ºC.

The Safe-T-Plus 259 Series offers a range of encapsulated

fuses designed to enable greater safety for operating electronic

equipment within potentially explosive environments. Originally

designed to serve the needs of gas plants, petrochemical and

processing industries, these fuses are certitifed for use within

intrinsically safe apparatus ATEx (EN 60079-0:2009 & EN 60079-

11:2007), IECEx) IEC 60079-0:2007 & IEC 60079-11:2006).

The fuse design and its encapsulant are suitable for use in

intrinsically safe appartatus for voltage not exceeding 125V rms

(190V peak).
