Original Manufacturer Description:


The PN-250B relay is a biased relay designed for use in line and logic  circuits. It is used in place of the PN- 150B relay when additional contacts are  required. Coils of this relay may be externally connected in series or in  multiple. For a relay that operates on lower energization values, the PN-250BE  relay is recommended. Contacts of the PN- 250B relay are standard low voltage  silver to silver-impregnated carbon front and silver-to-silver back. All PN-250B  relays incorporate Lexan® covers.
