SP4-1A adjustable, non-wired variable resistors for wall mounting.
Single-element single-turn resistors without a switch with circular movement of the rotary system and VS-2 shaft end.
Designed to operate in DC, AC and pulse current circuits.
Intermediate nominal resistances correspond to E6 series with the tolerances of ±20; ±30 %.
Available in all-climatic versions [V] and versions for temperate and cold climates [NF].
