The 3531114001 is a Series 140 barrier block designed for secure electrical connections. It features a voltage rating of 250 VAC RMS maximum and a current rating of 15 Amps maximum, accommodating wire up to #16 AWG. Constructed from a molded, general-purpose black phenolic rated UL 94V-1, this block operates over a temperature range of -55°F to +300°F. The interposing barriers between terminals provide higher electrical ratings and add protection against frayed wire shorting. This design allows equipment designers to choose a termination method suitable for specific environmental and manufacturing requirements.
