THERMAL MANAGEMENT SOLUTIONS EN-DigiTraceE507S2LS2-IM-H5691401/13
DESCRIPTION
The E507S-2LS-2 thermostat is designed for controlling heat-
tracing systems in hazardous locations. The thermostat functions
as a DPST switch. The DPST switch will enable and disable current
flow in both buses of the heat-tracing cable.
The E507S-2LS-2 can be used to control heat-tracing circuits in a
pipe-sensing mode (see Figure 1 on back page).
Note: Do not use this thermostat to control two separate heat-
tracing circuits.
